Specieaton of Letters Patent.

Application filed March 27, 1918, Serial No. 225,125. Renewed April 25, 1919'. Serial No'. 292,699:

curing means will loch the pump and thereby prevent either an accidental disengagement of the pump with the supporting means or an unscrupulous person from removing the same from the support.

An object of the invention is to provide a simple, uncumbersome and inexpensive device which can'be easily attached to a frame `ot" a bicycle or motorcycle.

Another object of the invention is to provide clamping means which are adapted to support the pump `and which have securing means in the restricted part ci' the clamps.

With the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts as herein fully described, illustrated and claimed.

In the accompanying drawings, forming part of the application, similar characters oi reference indicate corresponding parts in all the views.

Fig.` 8 is a Side elevation of the structure 'i shown in Fig. 7 i

Referring to the drawings, 9 is a tubular frame of a bicycle or motorcycle to which i a. clamp or a clip 10 is secured by means of a ring 11 open at cheeks 12 which extend from the ring to an arcuate branch 13 forming a yielding bracket or support for a` pump 14. The ring is locked to the frame 9 by means of a bolt 15 rthe head of which is elongated and provided with indentations 16 for engaging the edges of the cheeks. A washer 17 with similar indentations 16 is provided on the bolt for engaging the lower edges of the cheeks. These indentations permit the locking oi theringon tubular frames of varying diameters, as will be seen from Fig. 5. By locking the cheeks by means of the bolt 15` the rigidity of the bracket of the clip is also increased `at the cheeks. p

One of the branches 13 of the bracket has an end iange andl the other branch has a socket 19 at the end. A shank 20 is mounted to slide and turn in the socket-19. This shank forms one end of a fork 21, the other end 22 of which fork is bifurcated to iit over the flange 18 when the same alines therewith. The sliding movement of the stem is limited by a threaded member 23 provided at the extremity of same anda The fork 21 has a stem 27 the upperr end of which is shaped into a hook 28 for entering the other end of the pump 14. The lower end of the pump is preferably in threaded engagement with the fork so that the length of the portion above the fork may `be varied to suit pumps of different sizes.

The lower end of the pump is supported by a clip 29 secured to the frame 9. This clip is also secured by an open ring 30 one cheek of which extends from the ring and y carries a block 31 the other cheekn32 of which is maintained in proximity to the cheek carrying the block by means of a bolt 33 similar to the bolt 15 and carrying a similar washer. One face of the block 31 is beveled so as to be properly disposed for a'universal pump tip 34 which is disposed obliquely from the pump, as will be noted from Figs. 1 and 2. A suitable pin 35 is provided on the block for entering the tip and thereby locking the pump between the hook 28 and the clip 29. A pin 3G is also provided on the straight face of the block so that the saine may enter the lower end,VV

ries a spring 88 which normally forces the shank out of the sleeve thereby disengaging the other end 89 of the fork from the lock d() which takes the place of the flange 1S on the other branch of the bracket. AThis locking means, therefore, forms an integral part of the clip V10. 1t makes a more expensive article but it answers the same purpose as the structure described and disclosed in Figs, 1 to 5 inclusive. rlhe advantage of the preferred structure shown in Figs. 1 to 5 is that the lcclr can be selected by the owner to suit himself; and, further, it would per mit the use of the padlock 25 for locking the chain of the bicycle, which prevents the use of same by unauthorized persons. Y

When the pump is to be locked to the bicycle the branches of the clip are disengaged from the fork 21, and, therefore, by placing the lower end of the pump on the block 31 and forcing said pump between the branches 13, the pump will snap therebetween and be retained by the clip 10. The

fork 21 can then be raised and turned to bring the hook 28 into engagement with the scribed, thereby preventing an accidental' movement of the fork 21 and also tampering with same by unauthorized persons.

1 claim: Y
